I think I am going to start carrying my phone in a damn Faraday cage and only get it out when I want to make a call.

 

Prepare to welcome your new Robot Overlords:

If it'll walk my real dogs, can I buy one now?

 

Just ordered my first 3d printer. Crazy how much you can do with them.

 

What kind? I am thinking I will get one within the next year

 

Ender 3d Pro

This guy makes a great video on mods you can do to it by using it.

 

I want to get one just to print my own D&D minis.

 

I have an Ender 3 Pro. Feel free to ask questions.

 

Okay.

What is an Ender 3 Pro?

 

OK. Does dark matter exist or do we need to modify our theory of gravity to explain observations?

 

It's a 3D Printer by Creality. 225x225x250 headed build area, with a single z axis.

 

I mean, if you use black filament you could print the matter dark. But you can always paint stuff, so a good gray is a good base, for minis and stuff.

 

What is the difference between having multiple z axes and single z axis?

 

I took it to mean that it goes from "zero" to one other direction. E.g., it isn't going to print things both above and below the origin. So if you had something kind of complex, you would print it in halves or sections that you then glue together.

 

The weight on the gantry is all on one side on a printer, as that is where the filament spools in to, and where the extruder zeros.

If you have one z axis rod, the other side will inevitably dip, and get out of square, unless you've got all your wheels and eccentric bits locked down... and even then, eventually they will slip.

A second z axis rod will make that less of an issue, as the stepper will make both sides of the gantry rise and fall the same amount.

 

No. Has to deal with the gantry.

 

I'm trying to find visuals because I am not understanding your description.

 

This is a dual Z axis printer. See the labels for Z left and Z right. That cross bar that spans them, that is the X axis and controls the "printer head" that is the extruder, and the motor and all that. And it moves, if you are looking at the printer head on, left and right. That span is the gantry. And, in this one, the gantry is supported by two rods, going vertical, on the Z axis.

A one Z axis printer only has that on one side, and so that gantry can dip, and get out of square, because it isn't supported by a second rod. It's just the tension of the wheels that holds it in place. And since the weight is on the left, and then the X axis is moving around, the right side can slip. Dual Z axis printer typically doesn't have that problem, because it has that support.
